I am not able to get my email input even after defining my sessions, please look below:
I have two scripts: The first is is to show the declaration of the session, while the second is to display the session's value:
First Script:sessionTest1.php

<?php
session_start
();
?>

<html>
<head><title>Testing Sessions page 1</title></head>
<body>
<?php
$_SESSION
['session_var'] = "testing";
@
$_SESSION['session_var2'] = $_POST['email'];
echo
"This is a test of the sessions feature.
<form action='sessionTest2.php' method='POST'>
<input type='hidden' name='form_var'
value='testing'>
<input type='text' name='email'>
<input type='submit' value='go to next page'>
</form>"
;
?>

</body></html>

Second Script:sessionTest2.php

<?php
session_start
();
?>

<html>
<head><title>Testing Sessions page 2</title></head>
<body>
<?php
echo "session_var = {$_SESSION['session_var']}<br>\n";
echo
"session_var2 = {$_SESSION['session_var2']}<br>\n";
echo
"form_var = {$_POST['form_var']}<br>\n";
?>

</body></html>

Please what could be possibly wrong? or what should i do to obtain the entered value for the email and then be able to pass it along to as many pages as possible?

[Mod Edit: adjusted the code highlighting for the post]

First things first.... Do NOT use @ on a line unless you have a good reason. If you are using that, it usually means that you are not using good coding practices. In your code, you are using it to hide the warning that $_POST['email'] is set. This is just a big no-no in terms of good programming.

For this, instead you should actually be checking if it exists:

$_SESSION['session_var2'] = (isset($_POST['email'])) ? $_POST['email'] : FALSE;

Now onto the main issue you are having: You are having the form submit to sessionTest2.php, that is the script that will see $_POST['email']. There first one would only see it if you were coming from another page that had a form and it was set to post to it.

So move your session setting code for e-mail down to the second script, and it should set the session properly for you and then be available anywhere else the session is alive.
